How to fix a stiff slide problem on any mobile phone

When you slide up and slide down your mobile phone is the slide stiff, sticking and not smooth as it was brand new?

Well there is only one way to fix the slide being stiff, sticky or wobbly is to dissemble the mobile phone apart and replace the sliding mechanism with a brand new slide.When you buy a new sliding mechanism make its a original part.A original part on a mobile phone might be expensive to buy than copy parts.I say this because fake parts usually don't that long as original parts.You should not have a problem dissembling your phone because YouTube has loads of disassembly videos.
